Neil Horman 64e96ecf3c Make find-doc-nits compatible accross git versions
We recently found that the addition of a git config command in
util/find-doc-nits is broken in some cases, sepecifically because git
around version 2.46 broke command line compatibility, replacing the
--regexp option with the --get-regexp option.  So to maintain usage of
this specific command to parse the .gitconfig file, we would need to do
some extra version detection to construct the proper command line.

However, find-doc-nits already has a fallback condition, which does some
pure perl parsing of the gitconfig file, which works perfectly well.

Instead of trying to do version matching to construct the right form of
the git config command line, just remove it all, and rely on the perl
parrse to do this work for us, which works currently in all cases.

Fixes #29197
